July 28, 2009, Vancouver, BC - Taseko Mines Limited (TSX: TKO; NYSE AMEX: TGB) (“Taseko” or the “Company”) is pleased to provide the following update on its Prosperity Gold-Copper project.

The Prosperity Project is currently undergoing both a provincial and federal Environmental Assessment process. The Government of British Columbia process, being conducted by the Provincial Environmental Assessment Office, is expected to conclude by the end of October 2009. The Government of Canada process, a Federal Review Panel coordinated by the Canadian Environmental Assessment Agency, is expected to be completed in early 2010.

Russell Hallbauer, President and CEO of Taseko says, “Taseko has put forward an innovative and comprehensive fish and fish habitat management plan to compensate for the impact the project will have on the 111 hectare Fish Lake. Last week, on July 22, 2009, the Canadian Government’s Federal Department of Fisheries and Oceans (DFO) provided clarification on its evaluation of the compensation plan, advising that DFO will be guided by the fisheries objectives set by the Province of British Columbia, which is responsible for managing the fisheries resource affected by the development project. This clarification is an important step and consistent with the efforts both governments have been making over many years to achieve greater harmonization on such matters.

With both regulatory review processes continuing to move forward, the Company anticipates being in a position to make a decision on building the project in March of 2010.”

Several First Nations, including those in closest proximity to the project, are participating fully in the Federal Review process.
